The Next Standard.

The Crimson has a bold and captivating sound profile with an incredibly dynamic bass presentation, reminiscent of high-end speaker configurations. The inclusion of our PHAT technology allows the Crimson to build on Symphonium's signature treble response.

Crimson's treble is not only smooth but also well extended, offering class-leading resolution with a layered and spacious stereo image. With organic vocals, impeccable control and authority on the low end, the Crimson mimics the experience of standing in front of a live stage.

The combination of these characteristics makes the Crimson dynamically engaging and uniquely captivating to listen to.

"A close friend asked me right away what I did like about the Crimson and one of the phrases I told him was “It’s not cookie cutter. It’s new, it’s fresh, it’s the future.”, and I still live by those words. According to Symphonium brochures, it is the new standard, but I much rather prefer to call it the new benchmark."

Nymz Reviews

"Honing in on the Crimson’s sound only, it’s an IEM that captures the idea of colored, avant-garde sound to a very high degree. Listeners who want this type of presentation, and that tend to enjoy the pursuit of dialing in their preferred sound signature, will no doubt find the Crimson a strong purchase consideration."

Precogvision

"It’s hard not to give credit where credit is due: Crimson is probably one of the most spacious and enveloping IEMs I’ve heard. It actually mixes my favorite parts of Helios and Meteor’s technical performance in this regard."

Listener

"The resolution the Crimson provides is indeed top notch and I found it competes with some IEMs that come in at a high price. Overall, a wonderful tuning that is well executed."

Corgifall

"The Crimson has some innate soundstage that makes it characteristically different than many other earphones I've tried. That is -- it has a very interesting holographic soundstage that sounds quite large at times, but also puts certain elements closer into view."

FLAT + PHAT

Featuring a combination of our finest technologies, the Crimson boasts a fusion of both PHAT and FLAT advancements.

With PHAT technology ensuring no unnecessary frequency inversions or phase cancellation and FLAT technology ensuring low impedance and immunity from impedance mismatch - the Crimson is ready to take on any challenge thrown it's way.

Refined Shell Design

A different design language means a different look.

The Crimson proudly presents a redesigned shell, refined through extensive community feedback. The shell is now thoughtfully shaped to comfortably fit smaller ears, featuring a shorter nozzle and a gently rounded form.

The outcome is an IEM that rests snugly against the ears, ensuring a seamless fit. Made from the same high-grade T6 heat-treated AL6061 Aluminium alloy, the Crimson is engineered for durability and long-lasting performance.

Say Forged Carbon?

The Crimson boasts a new color scheme and a premium forged carbon faceplate that pays homage to our brand's origins and resilience.

This material composite has graced the works of award-winning jewelry, watch, and luxury vehicles. Due to the material's inherent nature, each faceplate is a unique masterpiece, ensuring no two sets are the same.

Given the Crimson's status, it's only fitting that this distinctive and premium material finds its place within the design.
